This invention relates to an improvement in radiator caps fo'automobiles. In the more general construction these caps are screwedinto the filling neck of the radiator. \Yhen unscrewed they are liableto be dropped and dilliculty is sometimes experienced in unscrewing. Theobject of this invention is to hinge the cap to the filling neck so thatitmay be, readily interlocked therewith and the neck opened whendesired, and the invention consists in the construction hereinafterdescribed and particularly recited in the claim.

The usual neck (3 has a collar 7 slightly larger in diameter than the.neck so as to t'orma shoulder 8 between them. Clamped around the. neckbeneath the collar is a band 9 formed from a strip of metal the ends eX-tended upward forming arms 10. The band is secured around the neck bymeans of a bolt ll and the upper ends of the arms are secured by a bolt.1'2. which also passes through the end of a cap strap 13 which is turnedat right angles to the main portion of the strap. which is secured to acap H formed from any suitable material and adapted to enter the collar7 so as to close the tilting opening. The strap also extends downwardand is formed with a shoulder 1.) adapted to spring under the lower edgeof the collar 7 beyond which it projects to form a finger-piece 1G. Thestrap is thus hinged to the collar, is always ready in position. andwhen closed is securely locked in place.

lclaim:

The, combination with a filling; neck formed with a collar, a bandsecured to the neck below said collar, the ends of the said band formedwith upwardly projecting integral arms. a strap having one end turned atright angles to the plane of the strap and secured to the upper ends ofsaid arms, a cap secured to said strap and adapted to enter said collar,said strap formed with a shoulder adapted to engage with said c0llarwhen the. cap is in place.
